Video-telephone system and its operation mode

Abstract

The present invention discloses a video-telephone system. Compared with the conventional video-telephone system, the video-telephone system disclosed by the invention, not only includes a video terminal, a bearing network and a communication server, but also includes a video processing device and a preset video media library. The communication server also controls all video stream transmitted from terminals to forward through the video processing device, except conventional authentication and call routing. The preset video media library records a variety of video media. The video processing device principally obtains a preset video media from the video media library, and then overlaps with media received from a video terminal, and then transmits out the video after processing. The present invention also discloses a operation mode of the video-telephone, when a video terminal initiates a video call, the communication server use signalling control to transmit video media of both sides of the communication to the video processing device for forwarding, the video processing device overlaps a preset media stream of the video media library onto each video media stream, and then forwards to the remote side of the communication. The present invention enables the video-telephone system to have a video advertising spreading function, which is propitious to commercialization applications.

Description

technical field [0001] The technical field of telephone communication involved in the patent of the present invention, in particular, relates to the video telephone system and its operation mode. Background technique [0002] Pure voice communication can no longer meet people's growing needs for rich and colorful communication. With the development of network communication technology, video communication has become possible. At present, there are many video phone systems or video communication systems that can provide video call services. . [0003] A traditional video phone system mainly consists of a video terminal, a basic bearer network and a communication server. The video terminal can call the peer through the communication server. The communication server addresses the peer through call routing and forwards the call request. If the peer agrees to receive The video and audio channels are established. The video terminal collects video signals and sends them to the com...

Problems solved by technology

[0004] The singleness of the technical model of the traditional video phone system is the same as that of the traditional voice phone. The phone service provider can only obtain commercial returns from the user, but the video phone system will occupy a relatively large bandwidth, which will definitely make the user bear more burden. The cost is even unacceptable, which makes it unfavorable for the business expansion of video telephony, and lacks a more effective business model, which hinders large-scale development to a certain extent
